DAKosKl ELECTRIC SWITCH OPERABLE BY ALARM CLOCKS Filed Feb. 8, 1945 ull/1111111111u1lill/111111111111111lill/1111100 Patented Mar. 30, 1948 UNITED STATES PATENT OFFICE ELECTRIC SWITCH OPERABLE BY ALARM CLOCKS The present invention relates to electric switches operable by alarm clocks, and has for its main object the provision of a simple and efficient device, operable by an alarm clock to con'- nect a switch, on an electric circuit, for lighting one or more electric lamps, or operating a radio, at a certain predetermined hour for which the alarm clock was set. t

With the above general objects in View and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout the severalviews;

Fig. 1 is a side elevational view of the present device, including an alarm clock set for operating an electric switch;

Fig. 2 is a top elevational view thereof;

Fig. 3 is a cross-sectional view on a horizontal plane, taken on line 3--3 of Fig. 1;

Fig. 4 is a cross-sectional view through the electric switch, when in an open position, taken on line 4-4 of Fig. 3;

Fig. 5 is a-similar view showing the switch in a closed position; and

Fig. 6 is a diagrammatic View of an electric circuit.

Referring in detail to the present drawing there is shown therein housing IU, to the top wall of which an alarm clock I I is rigidly affixed. Said alarm clock II is provided With an hour setting knob I2 and an alarm spring winding knob I3. The alarm clock II is further provided with knob I4 for stopping the alarm operating mechanism.

Made in the top wall of housing ID, and adjacent the rear end of alarm clock II, is an oblong slot I5 for the purpose which will be later Y apparent.

Axed to the bottom wall of housing I0 is supporting block I6, insulated from said housing tended over bolt Il, and is maintained in a clamped contactual position with said terminal I8 by means of nut 25. Connected with said eye I9iswire 2I.

Set upon said support I6 is block 22, likewise made of an insulating material. A hinged terminal generally indicated by 23 in Fig. 6, includes stationary leaf 24 which rests upon said block 22 and is passed through bolt 25 aixed to said block 22. Set over said bolt 25 andina contacting relation with leaf 24 is a metallic eye 26, maintained in position by nut 27 engaging said bolt 25. Wire 28 connects with said eye 26. Aiiixed to said leaf 24 and in a hinged relation therewith by means of pin 29 is an angularly shifting leaf 30. Said leaf 30 is adapted to make angular swinging motions, substantially to ninety degrees to assume either operative horizontal position, seen in Fig- 5, or inoperative, substantially Vertical position, seen in Fig. 4. When in that latter position, said leaf 3U bears against extension 3| made in leaf 24, which prevents said leaf 30 to make further shifting movement.

Wire 2| connects with a plurality of electric sockets 32. The last of said sockets 32 connects with wire 33. Wires 28 and 33 are made into cord 34, which extends through one side wall of housing I0, and is connected with an electric plug 35 which may be plugged to any electric outlet.

Sockets 32 are set within fixture 33 afixed to one of the side walls of housing I0. A radio or electric lamp, such as 31 may be connected with one or more sockets 32 by a plug such as 38.

Rigidly aflixed to alarm winding knob I 3, either permanently or disengageably, as at 39 is rod 40, the major portion of which is spaced away from alarm clock Il. Said rod 40 is in alinement `with slot I5, and'extends therethrough into housing I0. The lower end of said rod 40 is insulated as at 4I. Said rod 40 is adapted to make angular swinging movements in both directions,

and as far as the ends of slot I5 will permit. The object of said rod 43 is to trip leaf 35 and bring the same from its inoperative, vertical position, shown in Fig. 4, to the operative horizontal position shown in Fig. 5, for the purpose of completing the electric circuit illustrated in Fig. 6. When leaf 30 is in a horizontal position, the outer end thereof rests upon the vertical portion of terminal I 3, as is seen in Fig. 5, thereby completing the electric circuit and automatically lighting any lamps or operating any radios which may be connected with sock-J ets 32; To disconnect the circuit, and thereby extinguish any lamps or stopping the operation of any radios connected with any of the sockets 32 cord 4Z connected with leaf 3U is manually pulled at its opposite end, and which extends through one of the end Walls of housing Il), and which terminates in knob 43 so as to prevent said cord d2 from completely shifting into housing I0. When said cord 42 is pulled leaf 3Il will be shifted into its vertical position seen in Fig. 4, thereby circuit illustrated in Fig. 6 will be broken,

It is observed that when rod l0 is set into position seen in Figs. 1 and 2, it is in a prepared condition to strike leaf 33 when the hour for which the alarm clock was set arrives. When the hour for which the alarm clock was set arrives, the alarm spring unwinds, rotating knob I3, and thereby angularly shifts rod 46 until it comes to the position indicated by dotted lines in Fig, 1. When it comes to that position, it is stopped from 'further angular shifting movement by the body of the upper wall ofhousing I adjacent the end of slot I5,"thereby preventing said rod 45 from making further shifting movement. By that time leaf 39 has been brought by said rod 4I) into its horizontal and operative position shown in Fig. for closing the circuit illustrated in Fig. 6. To recondition rod 40, knob I4 is brought down so as to prevent further unwinding of alarm spring. VThereupon rod It is manually shifted until it is 'brought to the position shown by full lines in Fig. 1. In that position the opposite end of slot I5 limits further angular movement of said rod 4d, and rod l will remain in that latter position until the set hourr arrives to release the alarm operating spring, assuming, of course, that knob I 4 remains in a raised inoperative position. When said rod 4i! is reconditioned, as aforesaid, the position shown in full lines in Fig. 1, thereupon cord 42 is pulled to elevate leaf 30 and disconnect the same from terminal I3, to be again tripped and brought down into horizontal position by the renewedV operation of rod 4I) as aforesaid.

It is further observed that the alarm spring in alarm clock II is completely wound up by knob I3 before the alarm clock is aiiixed to the upper wall of housing I. When so aiixed, the alarm mechanism has no other purpose than to shift rod 40. Y Y

The device herein disclosed has particular yapplicationV and utility for persons who are deaf and for whom an audible alarm would have no object, but who are usually more sensitive to light, and who therefore are more readily aroused from slumber by the light, as well as for those persons Who would rather be awakened from sleep by sounds emanating from a radio than harsh alarm clock sounds.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit land scope ofthe invention as claimed.
